DESCRIPTION
The TLV238x single supply operational amplifiers
provide rail-to-rail input and output capability. The
TLV238x takes the minimum operating supply voltage
down to 2.7 V over the extended industrial temperature
range, while adding the rail-to-rail output swing feature.
The TLV238x also provides 160-kHz bandwidth from
only 7
µ
A. The maximum recommended supply voltage
is 16 V, which allows the devices to be operated from
(
±
8 V supplies down to
±
1.35 V) two rechargeable cells.
The combination of rail-to-rail inputs and outputs make
them good upgrades for the TLC27Lx family--offering
more bandwidth at a lower quiescent current. The offset
voltage is lower than the TLC27LxA variant.
To maintain cost effectiveness the TLV2381/2 are only
available in the extended industrial temperature range.
This means that one device can be used in a wide range
of applications that include PDAs as well as automotive
sensor interface.
All members are available in SOIC, with the singles in
the small SOT-23 package, duals in the MSOP.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. Relative to GND pin.
2. Maximum is 16.5 V or VS+0.2 V whichever is the lesser value.
